Gorilla Polyurethane Wood Glue

Gorilla Polyurethane Wood Glue

An all purpose polyurethane wood glue which is catalyzed by moisture. Once cured it is totally resistant to solvents yet excess can be easily removed with a scraper chisel or sandpaper. Strong and easy to use.

Polyurethane Glues - A long open time, one-part system, polyurethanes are simple and easy to use. It is ideal for laminations of pourous materials. Polyurethanes are water proof, but moistening the surface before adhering aids in curing.

Pros:
cheaper than epoxies, easy to clean up, water resistant, one-part, easy to use

Cons:
stains skin (gloves suggested), excess glue needs to chiseled out, more expensive than "Yellow Glues", requires moist substrates

• Take the time to complete this important step.
• Clean all surfaces and remove any dust, oil or other impurities. Use a solvent if necessary.
• Allow solvent to evaporate completely before applying glue.
• Make sure the pieces are tight fitting.
• Sand smooth surfaces or where there is a high oil/moisture content (e.g. in some woods, metals and plastics). The Glue needs something to adhere to.

• Spray or use a damp cloth to moisten one surface. Do not saturate.
• Let the moisture distribute before applying the glue.
• Moisture does not speed up the curing process but it allows for a chemical reaction to take place.
  

• Spread a thin layer of the Gorilla Glue onto the other surface.
• Spread the Glue using a disposable brush or with gloves.
• Remember, about half an ounce of the glue will cover a square foot. Do not over apply.
• Gorilla Glue will stain hands and ruin clothing. So wear gloves and protective clothing.

• You must clamp the pieces together. If you don’t have a clamp, apply heavy pressure.
• Gorilla Glue will foam about 3 to 4 times. So clamping is needed to keep the pieces together.
• Clamping pressure must be distributed evenly over the glue line area.
• Clamping time is always best at 68°F.
• Clamp for 3 to 4 hours and do not disturb the gluing items during this time.
• Leave the glued surfaces for about 24 hours for best results.
• Generally, clamping time has expired when the foam pressed out from the glue line feels dry and somewhat crisp.
• Foam in a glue line has no structural strength whatsoever, and must not be considered as a gap filler.

• The glue joint should be 90% cured within 4 hours, but for best results, leave for
  24 hours.
• The maximum water resistance of the glue line occurs after 5 to 7 days at 68°F.
  

• Squeeze air from the bottle.
• Secure the cap tightly.
• Store in a cool, dry place away from direct sunlight.
• Keep out of reach of children and animals.
• If you are using Gorilla Glue for the first time, or using a material you are unsure about, always try a test piece first to ensure suitability.
